Bridged ETH from Etherium to WETH in Axax, but only the 1 of 2 t stated that it would occur in two transactions, but only 1 of 2 occured. Now I have WETH in my Etherium Mainnet, and its gonna cost a fortune to bridge that over to Avax again. Any solutions?

Your wETH should be in Avax C chain if you used the bridge. Connect your wallet to Pangolin and check. Use Pangolin to swap wETH to AVAX but you should have some AVAX to pay gas fees.
